Electric Center Line Butterfly Valve — Versatile Control for Standard to High-Temperature Media
The Electric Center Line Butterfly Valve (also known as a concentric butterfly valve) features a symmetrical disc-and-stem design where the stem, disc, and body centerline align on the same axis. This straightforward, proven construction makes it one of the most widely used valve types in general industrial service — offering a cost-effective, low-maintenance solution for isolating or regulating flow in pipelines carrying water, air, steam, oils, and various process media.
Driven by an electric actuator, this valve is available in two control modes to match different automation needs: switching type for simple open/close (on/off) operation, and regulating type for precise, modulating flow control. This flexibility allows the same valve platform to serve both basic isolation duties and more demanding process control applications, giving engineers a single reliable valve family to specify across multiple system requirements.
